A vertically-oriented blade fuse system requires less surface area on a printed circuit board, provides improved heat dissipation, is less expensive to manufacture and assemble and is more reliable. It comprises a fuse having two connection plates that extend away from each other in opposite directions. One of the plates is forced into a fork-shaped connector, which grabs both sides of the plate. The other connection plate is fit into a mating female connector. Multiple vertically-oriented fuses, laterally spaced from each, are connected to corresponding connection forks and female connectors inside a housing, which can be latched to a circuit board.

A sealed fuse in accordance with the present disclosure may include a tubular fuse body, a trench formed in an exterior of the fuse body, and an electrically conductive endcap that fits over an end of the fuse body and is fastened to the fuse body by an electrically conductive material having a lip portion that extends into the trench to provide a barrier that extends between the fuse body and the endcap. In an embodiment, the trench may be formed in an end face of the fuse body and may extend entirely around an opening in the end of the fuse body. In another embodiment, the trench may be formed in an outwardly-facing surface of a sidewall of the fuse body and may extend entirely around the fuse body.

The blinking device includes multiple power terminals, multiple load terminals, multiple contact switches, a control circuit, and multiple mounting substrates, and a case in a box shape for accommodating these therein. The multiple contact switches are individually associated with multiple power supply paths individually connected to multiple pairs each defined as a pair of one power terminal of the multiple power terminals and one load terminal of the multiple load terminals. At least one power supply path of the multiple power supply paths is formed on at least one of a front face, where at least one contact switch is mounted, and a rear face, where no contact switch is mounted, of each of the multiple mounting substrates. The case is configured to accommodate the multiple mounting substrates so that the multiple mounting substrates are stacked in a thickness direction.

In order to provide a method for isolating a circuit and a thermal link, wherein the link has a very low resistance and is suitable for high currents, in particular very high short load currents, and also has a high degree of reliability, in particular under difficult conditions, such as thermal and mechanical loading which lasts for a relatively long time, for example, the invention proposes that, during the phase transition of the material of the fusible element (10) from the solid to the liquid state, the volume of the fusible element (10) increases and the pressure increases and, owing to the increase in volume and the increase in pressure, the fusible element (10) is dislodged so as to break the electrical connection.

An electrical fuse (100) comprising: an electrical conductor element (108) comprising a melting section (110) and further comprising a first extension section (112) and a second extension section (114) both integrally formed with the melting section (110) and extending from both ends of the melting section (110) in the lengthwise direction thereof, an electrically insulating, multi-part housing (102), which encloses said melting section (110) in an interior space (116), wherein the multi-part housing (102) comprises a first part (104) and a second part (106) slidingly engaged with said first part (104) and arranged such that the second part (106) covers an access opening (118) of the first part to the interior space (116), and wherein the first extension section (112) and second extension section (114) comprise a terminal area, respectively, both terminal areas are arranged outside the multi-part housing (102).

Provided is a chip fuse and a method for producing the same, which is improved to facilitate balanced release of impact and vapor generated upon fusion. The chip fuse includes a fuse body having a pair of facing upper and lower ceramic substrates, a fuse wire support having a vertical through hole in its center and held between the ceramic substrates, and a fuse wire mounted between the two ends of the fuse wire support across the through hole, and a pair of metal caps fitted on the two ends of the fuse body, wherein the upper ceramic substrate and the fuse wire support, and the lower ceramic substrate and the fuse wire support, are respectively adhered together on their mutually facing surfaces to hermetically close the through hole, partially leaving a non-adhered region on the adhered surfaces.

A fuse includes a fuse body, two terminals, and a termination reinforcement. The fuse body surrounds a fusible element. The first terminal is located at one end of the fuse body and the second terminal is located at the other end of the fuse body. The fusible element is mechanically connected to the first and second terminals. The termination reinforcement is located at one end of the fuse body.
